It would be great if somehow they found an anti-zombie solution; accessed an old missile silo and fired it into the stratosphere to stop the zombie virus.
It’s been ten years. No one talks about how the biology of a zombie would maintain itself. I would imagine some parts of the body would need repair. Also, without any consumption of energy laden “food” how do they move!
After ten years the hordes would be thinned. Groups of people would establish a defendable community and trade would be restarted.
The dictatorships would not be a brutal as labor would be needed and babies would be at a premium.
I liked the show. When it went woke, the writing decline. Some episodes I have to wonder if I need a maxi pad to get through it all.
Bring it to a dignified end to a great TV series...
